摘要:
A compactly designable optical system for ophthalmological instruments comprising an illumination system so adapted as to illuminate a fundus with rays having passed through a ring slit and been focused on the cornea of an eyeball to be examined, and an observation/photographing system so adapted as to permit observing and photographing an image of said eyeball with a small reflector mirror arranged in said illumination system so as to be inclined with regard to the optical axis thereof and a relay lens for focusing the rays which are reflected by the fundus, passing through said objective lens and reflected by said small reflector mirror.

A position input device is provided in which signals are transmitted from a position indicator, and signals transmitted from the position indicator are received by a position detector device. According to certain embodiments, an electrical double-layer capacitor, a charging circuit which charges the electrical double-layer capacitor, and a power transmission unit which relays and supplies to the charging circuit power supplied from a power supply unit external to the position indicator, are provided in the position indicator. In other embodiments the position input device has a built-in power supply unit, transmitting units, and a control unit for switching the transmitting units between energized and de-energized states. Also provided are position input systems and computer systems including the position input device, and methods of operating the position input device and the systems.

Provided are an information input device, an on-screen arrangement method thereof, and a computer-executable program capable of preventing deterioration of operability even when an input disable region is set on a touch panel. An information input device capable of inputting information by an indicator touching a touch panel formed on a display screen includes an input disable region setting controller that sets an input disable region on a part of the touch panel and a display controller that rearranges an object being displayed on the display screen to avoid the set input disable region.

An approach is provided that filters out inadvertent contact with a touch pad input device. A filter area is defined within a surface of a touch pad input device that is accessible from an information handling system, such as a computer system. When a user of the information handling system contacts the surface of the touch pad, an input stream is received. The input stream includes an origination point where contact was initially made by the user. If the origination point is within the defined filter area, then the input stream is filtered out (not processed). On the other hand, if the origination point is outside of the defined filter area, then the input stream is processed by the information handling system.

Systems and methods are disclosed herein that generally involve allowing movement of windows or other user interface objects back and forth between a touch screen display and a non-touch display using only touch inputs. In one embodiment, a “send” touch gesture performed on a window displayed on the touch screen display causes automatic movement of the window to the non-touch display. A tab corresponding to the moved window is then displayed on the touch screen display. The tab can be used to interact with the window using touch inputs, even though the window has been moved to a non-touch display. For example, a “retrieve” touch gesture can be performed on the tab to move the window back to the touch screen display, or a “select” touch gesture can be performed on the tab to bring the moved window to the front and give the moved window focus.
摘要:
A display device for displaying information thereon, comprising a display unit adapted to display information in a plurality of display orientations, an orientation determination unit adapted to determine a physical orientation of the display device, a touch sensor adapted to sense a touch input from a user, and a display controller adapted to rotate the information displayed by the display unit from a first display orientation to a second display orientation when the orientation determination unit determines a change in the physical orientation, wherein the display controller suspends rotation of the information displayed by the display unit in the first orientation when the touch sensor senses a touch input substantially contemporaneously with when the orientation determination unit determines the change in the physical orientation.
